Abstract
The invention discloses a counterweight-type constant-tensile-force rubber belt tensioning device for a coal mine underground belt conveyor, and relates to mining machinery. The counterweight-type constant-tensile-force rubber belt tensioning device comprises a machine frame, a winch and a counterweight. The winch is arranged on the machine frame, two movable pulleys are arranged at the front end of a tensioning trolley, a fixed pulley is arranged on the machine frame, a steel wire rope is wound around the movable pulley I, the fixed pulley, the movable pulley II, a steering pulley set, a guide wheel I and a guide wheel II and lifts the counterweight, and the automatic tensioning function of a rubber belt of the belt conveyor is achieved. The weight of the counterweight is determined according to the power of the belt conveyor, the weight of the counterweight is equivalent to tensile force, and therefore the tensile force is constant. The lower end of the counterweight is provided with a sudden stop switch matched with a belt breakage protection system of the belt conveyor, so that once the belt is broken, the counterweight falls off immediately, and the sudden stop switch is triggered. Immediate stop is achieved when the belt is broken, and a belt breakage protection device is started so that the belt can be captured immediately.
Description
Technical field
The present invention relates to a kind of mining machinery, specifically the weight Combined constant tension force tape tensioning device with broken belt protector function for a kind of Belt Conveyors Underground Coal Mine.
Background technology
At present belt conveyer is as the down-hole mechanical main transportation device of mining, and it mainly plays the effect of transport coal.Tightening device is as one of underground belt conveyer necessary parts, and it can provide enough reasonably tension force for the normal operation of travelling apron.Tensioning mode mainly contains winch take-up and hydraulic tensioning; Winch take-up is fixed tensioning, because adhesive tape has certain elasticity, when operation, slides between adhesive tape and cylinder for preventing, must on the basis of normal tension, suitably strengthen winch take-up power, guarantees the normal operation of equipment.Hydraulic tensioning is auto-tensioning, but hydraulic system structure complexity, and Hydraulic Station, oil cylinder, energy storage maintenance difficulties is large, maintenance intervals is short; Once a place goes wrong, automatic tensioning function is not just realized, and has become fixed tensioning, and the degree of tightness of adhesive tape is not accomplished to summary responses.The winch take-up and the hydraulic tensioning that use at present, do not possess the function of broken belt protector.
Summary of the invention:
In order to solve the problems of the technologies described above, the invention provides the Belt Conveyors Underground Coal Mine permanent tension force tape tensioning device of weight hammer type that a kind of function with the permanent tension force auto-tensioning of adhesive tape has again broken belt protector function.
The present invention is achieved through the following technical solutions: the permanent tension force tape tensioning device of weight hammer type for a kind of Belt Conveyors Underground Coal Mine, the adhesive tape of belt conveyer and belt feeder bend pulley are arranged on tensioning car, and the outer end of tensioning car is connected with tape tensioning device by steel rope.It is characterized in that: described tape tensioning device comprises: frame, winch and weight.Described frame is steel structure rectangular frame, and frame is fixed on the basis of tensioning car front end.Described winch is arranged in frame.Described tensioning car front end is installed movable pulley, and deflection sheave group is installed in one end that described frame and winch are adjacent, and track adjusting wheel I and track adjusting wheel II are installed in the upper end of frame.One end of described steel rope is wrapped on winch, and the other end of steel rope is walked around described movable pulley, deflection sheave group, track adjusting wheel I and track adjusting wheel II weight is sling.The lower end of described weight arranges emergency stop switch; Described emergency stop switch is arranged in frame.
Described movable pulley has two groups of movable pulley I and movable pulley II; Fixed pulley is installed in one end that described frame and winch are adjacent, and described steel rope is walked around successively movable pulley I, fixed pulley, movable pulley II, deflection sheave group, track adjusting wheel I and track adjusting wheel II weight is sling.
Good effect of the present invention is:
1, ensure by the weight of adjusting weight the constant-tension that adhesive tape is required, the degree of tightness of adhesive tape is accomplished to summary responses, do not need additionally to increase tightening force, increased the safety factor of adhesive tape, improved the safety of equipment.
2, emergency stop switch coordinates with belt conveyer broken belt protector system, once there is broken belt, weight drop, touches emergency stop switch, realizes broken belt and immediately stops and start belt break protection device adhesive tape is arrested immediately.
3, simple in structure, compact, physical construction dependable performance, has reduced the maintenance time of equipment.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the birds-eye view of Fig. 1.
In figure: 1, tensioning car, 2, deflection sheave group, 3, frame, 4, weight, 5, winch, 6, steel rope, 7, emergency stop switch, 8, belt feeder bend pulley, 9, adhesive tape, 10, movable pulley I, 11, fixed pulley, 12, movable pulley II, 13, track adjusting wheel I, 14, track adjusting wheel II.
Detailed description of the invention
As shown in Figure 1 and Figure 2: the permanent tension force tape tensioning device of weight hammer type for a kind of Belt Conveyors Underground Coal Mine, the adhesive tape 9 of belt conveyer and belt feeder bend pulley 8 are arranged on tensioning car 1, and the outer end of tensioning car 1 is connected with tape tensioning device by steel rope 6; It is characterized in that: described tape tensioning device comprises: frame 3, winch 5 and weight 4.Described frame 3 is steel structure rectangular frame, and frame 3 is fixed on the basis of tensioning car 1 front end.Described winch 5 is arranged in frame 3.Described tensioning car 1 front end is installed movable pulley, and deflection sheave group 2 is installed in one end that described frame 3 is adjacent with winch 5, and track adjusting wheel I 13 and track adjusting wheel II 14 are installed in the upper end of frame 3.One end of described steel rope 6 is wrapped on winch 5, and the other end of steel rope 6 is walked around described movable pulley, deflection sheave group 2, track adjusting wheel I 13 and track adjusting wheel II 14 weight 4 is sling.Weight and steel rope 6 by weight 4 between winch 5 and tensioning car 1 are strained, and this tightening force is delivered in conveyor belt running 9, have realized the automatic tensioning function of adhesive tape 9.Determine the weight of weight 4 according to the watt level of belt conveyer, the weight of weight 4 is tensile force, therefore tensile force is also constant.
The lower end of described weight 4 arranges emergency stop switch 7; Described emergency stop switch 7 is arranged in frame 3.Emergency stop switch 7 is connected with belt conveyer broken belt protector system; once there is broken belt situation; weight 4 falls immediately; weight 4 touches emergency stop switch 7; broken belt signal is delivered to belt break protection device by emergency stop switch 7; realize belt conveyer and immediately stop, and start belt break protection device adhesive tape is arrested immediately.
Because the weight of weight 4 is excessive, the pulling force of the carrying of steel rope 6 is subject to the restriction of winch 5, the present embodiment is installed two groups of movable pulleys on winch 5, be movable pulley I 10 and movable pulley II 12, a fixed pulley 11 is installed in described frame 3, and steel rope 6 is walked around successively movable pulley I 10, fixed pulley 11, movable pulley II 12, deflection sheave group 2, track adjusting wheel I 13 and track adjusting wheel II 14 weight 4 is sling.Make the pulling force that steel rope 6 carries be equivalent to 1/4th of weight 4 weight.The applicant thinks, movable pulley more than two is installed on winch 5, for reducing steel rope 6 pulling force, also in the scope of the disclosed technical scheme of the application.
